Your pituitary gland is a pea-sized gland at the base of your brain. It has been recommended in the current Clinical Afenoma Guidelines by the Endocrine Society – a professional, international medical organization in the field of endocrinology and metabolism – that all patients with pituitary incidentalomas undergo a complete medical history and physical examinationlaboratory evaluations to screen for hormone hypersecretion and for hypopituitarism.

Clinical manifestations include truncal obesity with thin extremities, thinning of the skin, osteoporosis, and a tendency to bruise easily. Pituitary adenomas are generally divided into three categories dependent upon their biological functioning: A benign or malignant neoplasm affecting the pituitary gland.

It is not uncommon for them to be discovered at autopsy. The hormones vasopressin and oxytocinproduced by the neurons of the supraoptic and paraventricular nuclei of the hypothalamus, are stored in the posterior lobe and released from axon endings dendrites within the lobe.
